RE: User Defined Variables within SOLVE Application
Hi Michael,
I've been looking at this as well. Im no expert, just learning from scratch. It seems that although you can save an equation as a Home User Variable, say using F_P1:=fv=pv*(1+rate)^periods, you will have issues:  You get a syntax error after you store the equation  even though it shows up in User Var properly  If you try to assign it to a Solver APP with say Solve.E1:=F_P1 you will see 0 in E1: of the Solver App. Looks like its evaluating the variables ahead of time  You get a syntax error if you try to type the equation (fv=pv*(1+rate)^periods) directly into Solver APP So, I have tended to use CAS mode and saved equations in CAS variables:  F_P1:=fv=pv*(1+rate)^periods // stores in Vars>CAS>All  Solve.E1:=F_P1 // stores F_P1 contents into Solver APP E1:  In Solve APP, will ask you to create new user vars fv, pv, rate, periods. say yes.  Solver APP now works. Note  you can add multiple/simultaneous equations.  You may want to delete the new User Variables just created after leaving Solve APP. Best, Carl
